They installed a 19K SANYO Flexi-multi outdoor unit and two SANYO fexi-multi indoor units about 4 years ago, a great split system for two rooms. The system replaced two through the window air conditioners. Their salesmen are very knowledgeable, had great suggestions about how and where the units should be installed. The installers worked professionally, tested the system to make sure that the system worked perfectly, and we understood its operation before they left. We also were given help obtaining Con Ed. rebate of $400.00. We have four more rooms to air condition in the same way, and when we're ready, they're the ones to call.
